What is the AST for decorator in typescript?

Question

I need to know what is the AST name of the typescript decorators?

I need it for the ESLint selectors.

I saw a tool somewhere but I can't find it

Answer 1

Decorators are available on the modifiers of the decoratable node. There is a ts.getDecorators helper method you can use to access them though:

const classDecl: ts.ClassDeclaration = ...;
const decorators = ts.getDecorators(classDecl);
// use decorators here

This is the type of ts.Decorator:

export interface Decorator extends Node {
    readonly kind: SyntaxKind.Decorator;
    readonly parent: NamedDeclaration;
    readonly expression: LeftHandSideExpression;
}
